Replacing a system fan

Use this information to replace a system fan in the server.

Read the safety information in Safety and Installation guidelines.

If you are replacing a server component in the server, you need to turn off the server and peripheral devices, and disconnect the power cords and all external cables.

Attention

Static electricity that is released to internal server components when the server is powered-on might cause the server to halt, which might result in the loss of data. To avoid this potential problem, always use an electrostatic-discharge wrist strap or other grounding system when you work inside the server with the power on.

To replace a system fan, complete the following steps.

1. Position the replacement fan so that the airflow arrow on the fan points toward the rear of the server.
   Note

   The correct airflow is from the front to the rear of the server.

2. Install the replacement fan in the bracket:
   1. Make sure that the fan cable sits in the channel on the side of the fan.
   2. In the location from which you removed the failed fan, route the fan cable into the fan cable slot in the fan bracket top.
   3. Insert the fan into the bracket.
   4. Make sure that each of the grey soft tabs on the fan is fully seated in its slot in the fan bracket.
3. Connect the replacement fan cable to the system board (see System-board LEDs for the locations of the fan cable connectors on the system board).
4. Reinstall the air baffle if it was removed before (see Replacing the air baffle).
5. Reinstall the cover (see Replacing the cover).

If you have replaced a server component or installed an optional device in the server, you need to reconnect the power cords and all external cables, and turn on the server and peripheral devices.
